Astronaut Mark C. Lee, payload commander, on the end of the Remote Manipulator System (RMS) arm, photographs a bit of patch work on the worn insulation material of the Hubble Space Telescope (HST). The rectangular patch is on HST’s Bay 8. Astronaut Steven L. Smith (out of frame), mission specialist, assisted with the patch work. This was the final Extravehicular Activity (EVA) of five performed by two teams of space walkers on the mission.
